Compressions
my teacher uses the same site for worksheets too email e if u get any more answers in feb im in waves
In a longitudinal wave, the particles do not move with the wave. The particle movement is parallel to the direction of the wave propagation. This means that the particles move left and right which in turn makes the other particles start to oscillate. This creates a wave. longitudinal pressure waves are also known as sound waves.
I think you are referring to a "Megalopolis"
yes.they are pact together like thousands of ball in a package
Particle spacing is the closest together in solids. In liquids the spacing is close, however the particles have the freedom of movement. In gas, the particles have lots of kinetic energy, therefore they are far apart.
high sound particles are near, and low sound as far apart particles.
It is called a compression.
Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
Just had this lesson this afternoon, 06.23.2009. Longitudinal/compressional waves were drawn as a spring. The rarefaction is drawn as the expanded part of the spring and the compression as the compressed part.

Compressions are the parts where the coils are close together
if you squeeze a part of the spring close together the other part of the spring is going to be more apart .

Spring hinges close doors automatically.
The black things that come together to close, and open by squeezing the middle are cologne containers.
